The science of sound


Science at the service of musicians

Innovations in the field of musical instruments in the last century were mostly focused on electronic music. Pauline and Maxime, two researchers and musicians passionate about acoustics, created SYOS (Shape Your Own Sound) in order to bring innovation in the making of acoustic instruments.


A new way to design instruments

Pauline and Maxime noticed that today, few musical instruments are really optimized, that's why they decided to imagine a creative method based on a scientific approach to musical instruments, and especially on acoustic and psychoacoustic studies. This leads to innovative instruments that are closer to the musicians' expectations.

A custom geometry, 1/100 mm accurate!

For wind instruments, the sound is shaped by the internal geometry of the instrument, not by the material in which the instrument is made. The material used to create SYOS mouthpieces is the ABS plastic. We use 3D printing to make the mouthpieces ourselves, which allow us to:

  • Design a unique mouthpiece for each musician
  • Reach an accuracy superior to 1/100 mm
  • Craft mouthpieces that are 100% reproducible

The ABS we use to create SYOS mouthpieces has been certified non-toxical (EN 71 and CE 1907/2006 standards) in laboratory. All our mouthpieces are designed and created in our workshop in Paris.
